Patented Feb. 25, 1908 To -all whom it may concern:

Be it known that '1, PAU AYR ES, a citizen of the United States, and aresident of Ocean Side, in the county of Nassau and State of New "York,have invented a new and Im- I proved Drum-Trap, of which the followingis a full, clear, and exact-description.

The object of the invention is to provide a. new and improved drum trapfor use on bath tubs,- basins, kitchen sinks, urinals and like screwingthe cover in position on the threaded ring held against turning in thelead casing,

matter.

portions of the lead material of the casing extending over the top ofthering to'form an inte'gral washer for the cover to rest agai-nst,

to prevent le'akageof gas orother I in the direction of the height ofthe flange,

With-a view [The invention consists of novel features and parts andcombinations .of the same,

. which will beIhQre fully described hereinafter and thenpointed out in.the claims.

A practical I embodiment of the invention is represented in theaccompanying drawings forming a part of thisspemficationfin Wll-lCllsimilarcharacters of reference indicate corres onding partsin alltheview's.

- igure 1 isasectional side elevation of the improvement on thelin'e 1-1 of Fig. 2, part of the casing: being shown in elevat1on; Fig. I 2 isa sectional plan view of the same on the line 2'2 of Fig. '1 ,oan'd Fig.3 is an enlarged I side elevation of an'internallythreadedring ;thecover (l forlclosing thetrap, the said em loyed. I

I n the mouth of the lead casing A fits an internally thre'aded'ring -Bin which screws ring B and the cover Q being-preferably of metalharder-thanthesoft metal casing A.

over the top thereof, so' that tions B thussecurely locking thering'Bfin The ring B is provided with an external flange B havingindentations B ,-as plainly shown in the drawings, and the external'diameter of thering Bis approximately the. same as the external diameterof-the casing: A, so as to fit the ring B into. the casin -up to thebeginning of the flangeflB en.

this has been done the casi -m ateri'al is drawn or spun over the flangeand drawn portions A of the casing'material pass, into the indenta--place in the casing,to prevent the mug rrom turnlng when the cover 0- 1Sscrewedln posi' tion to closethe casing. .The casing ma-' terial. Adrawn over the top of-the ring B forms, a natural Washer for the flangeC of the cover O'to rest against, with a view to revent leakage of gasand other matter om the trap. By the arrangement described, theinternally ithread'ed ring B is securely fastened in place in the mouthof the casing A, to permit of tightly screwing the cover 0 in placeon'the 'ring'B, at the same time abutting the flange O of the cover 0against the washer material A, to.

prevent leakage, as reyio'usly mentioned.

By reference-to ig. 3' it will be noticed that the indentations B? areoblong, range B, begin at the lower edge thereofto form a ready openentrance for the lead material, and the indentations terminate adistance from the top of the flange B so that the lead readily enterstheindentations on s inning the material over the flange B', an at thesame time the rin B is securely locked- By the arrangefitting intothemouth of the casing and the.
